Abstract

The invention discloses artificial stone and a production method thereof. The artificial stone comprises the following raw materials in percentage by weight: 40-60% of unsaturated polyester, 0.1-1% of a silane coupling agent, 0.1-3% of an accelerator, 0.1-3% of a curing agent, 0.1-3% of an antifoaming agent, 40-50% of inorganic minerals and 1-3% of graphene based on the weight of unsaturated polyester. According to the artificial stone and production method thereof disclosed by the invention, the adopted components are odorless, pollution-free and harmless to environment and human bodies, the problems such as shrinkage and deformation are avoided in use, and pollution to water quality and soil is prevented after the artificial stone is discarded.

Description

Rostone and manufacture method thereof

Technical field

The invention belongs to building material technical field, specifically, relate to rostone and manufacture method thereof.

Background technology

In recent years, along with the development of national economy, the raising of people's living standard, Engineered stone products is more and more approved by market, along with these products a large amount of enter average family, hotel and Business Building, the environmental protection problem that it brings displays gradually.

Its main material of Engineered stone products can be divided into two large classes in the market: the first kind is organism bonding, main material adds resin polymerization with sandstone powder or water-ground limestone, its shortcoming is: have the chemical odor of can't get rid of all the year round, to indoor environment and human body, there is certain injury, and all will pollute water quality, soil after discarding, the contraction that next its product produces, problem on deformation also cannot solve.

Equations of The Second Kind is mineral compound, is mainly used in board materials production, its product must in kiln high temperature sintering shaping, its major defect is that arc stone material and moulding series products all can not be processed.

Summary of the invention

Instant invention overcomes shortcoming of the prior art, provide rostone and manufacture method thereof, there is no smell, pollution-free, environment and human body are not injured, and its production process is simple, is easy to processing, low cost of manufacture.

In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:

Rostone, its raw material and raw material weight percentage composition as follows:

Unsaturated polyester 40-60%;

Silane coupling agent 0.1-1%;

Promotor 0.1-3%;

Solidifying agent 0.1-3%;

Defoamer 0.1-3%;

Inorganic mineral 40-50%;

Also add the Graphene of 1 ~ 3% of described unsaturated polyester weight.

Further, described inorganic mineral, according to 100 parts, comprises 20-30 order quartz sand 40-45 part, 30-50 order quartz sand 15-20 part, 50-80 order quartz sand 15-20 part, 80-100 order quartz sand 15-20 part.

Further, described promotor is cobalt system metal organic salt, and described solidifying agent is Diisopropyl azodicarboxylate, and described defoamer is silicone emulsion or the fatty acid ester compounded thing of higher alcohols.

Further, described unsaturated polyester is 50%, silane coupling agent 0.5%, promotor 2%, solidifying agent 1%, defoamer 1.5%, inorganic mineral 45%, described inorganic mineral comprises 20-30 order quartz sand 42 parts, 30-50 order quartz sand 18 parts, 50-80 order quartz sand 20 parts, 80-100 order quartz sand 18 parts, and adopt this component, rostone in use can not produce the problems such as contraction, distortion.

The manufacture method of rostone:

(1), be uniformly mixed under vacuum or normal pressure by formula constituent;

(2), above-mentioned mixed material is built shaping, or by above-mentioned mixed material transfer to vacuum press compression moulding, heating make its primary solidification, and then raised temperature carries out after fixing;

(3), the demoulding, fixed thick, polishing, obtained finished product.

Further, the envrionment temperature when primary solidification remains on 50 ~ 90 DEG C, and envrionment temperature during after fixing temperature remains on 80 DEG C ~ 140 DEG C.

Further, in described step (2), described vacuum tightness is-0.03 to-0.1MPa

Compared with prior art, the invention has the beneficial effects as follows:

Rostone of the present invention and manufacture method thereof, the component of employing does not all have smell, pollution-free, does not injure environment and human body, in use can not produce the problems such as contraction, distortion, and all pollution-free to water quality, soil after discarding.
